about
the
necessity
to
install
service
lines.
For
service

we
recommend
using
multi

SECURITY
LINE
(STOP
BUTTON)
The
security
line
serves
to
output
the
signal
from
the
STOP
button
located
in
the
dispenser
to
the
station
switchboard
security
circuits.
The
security
line
must
be
especially
installed
in
LPG
and
CNG
dispensers/modules
that
operate
in
an
unattended
mode.
Pressing
the
STOP
button
on
the
dispenser
activates
the
security
circuits
that
disconnect
the
dispenser
from
the
power
supply
and
at
the
same
time
the
safety
valves
on
the
supply
line
close.
In
order
to
install
the
security
line
it
is
necessary
to
route
the
3
‐
wire
power
cable
H05VV5
‐
F
3x1.5
(see
Table
22)
to
each
dispenser
at
the
fuel
station.
The
security
line
cable
is
always
brought
from
the
main
switchboard
in
the
booth
to
the
first
module
of
the
dispenser
into
the
distribution
box.
From
the
distribution
box,
the
cable
is
routed
to
the
dispenser
electronic
head
where
it
is
connected
to
the
STOP
button.

REGULATION
OF
VALVES
IN
PRESSURE
SECTIONS
OUTSIDE
DISPENSER
(CNG
MODULE)
If
the
valves
from
high
‐
pressure
sections
are
located
at
the
CNG
fuel
station
outside
the
dispenser
in
the
area
of
pressure
reservoirs
and
compressor
then
their
switching
is
performed
by
a
5
‐
wire
H05VV5
‐
F
5G1.5
cable
(see
Table
14).
The
cable
from
valves
regulation
is
routed
from
the
main
switchboard
in
the
booth
to
the
supply
distribution
box
of
the
dispenser.
The
H05VV5
‐
F
5G1.5
cable
is
routed
from
the
distribution
box
to
the
counter
case
to
the
outputs
that
ensure
the
valves
regulation.

with
maximum
current
‐
carrying
capacity
of
0.8

.
Always
consult
